我正在使用以下代码直接打开图库应用程序以从图库中选择图像。但它提供了另一个选项，如屏幕截图所示。

在此处输入图像描述

那么是否可以直接打开图库应用而不显示任何选项？我使用的代码如下所示。

Intent imageintent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
imageintent.setType("image/*");             
imageintent.putExtra("crop", "true");
imageintent.putExtra("aspectX", 1);
imageintent.putExtra("aspectY", 1);
imageintent.putExtra("return-data", true);
startActivityForResult(imageintent, SELECT_IMAGE);

这是您的问题的解决方案，只需按照以下步骤操作。

布局.xml

 <ImageView
                    android:id="@+id/circleImage"
                    android:layout_width="@dimen/d109dp"
                    android:layout_height="@dimen/d109dp"
                    android:layout_gravity="center_horizontal"
                    android:layout_marginTop="@dimen/d10dp"
                    android:src="@drawable/man"
                    app:civ_border_color="@android:color/white"
                    app:civ_border_width="@dimen/d2dp" />

MainActivity.java

 case R.id.imageButtonEdit:
            final CharSequence[] items = {"Take Photo", "Choose from Library",
                    "Cancel"};

            AlertDialog.Builder builder = new AlertDialog.Builder(EditProfileActivity.this);
            builder.setTitle("Add Photo!");
            builder.setItems(items, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int item) {
                    boolean result = Utility.checkPermission(EditProfileActivity.this);

                    if (items[item].equals("Take Photo")) {
                        userChoosenTask = "Take Photo";
                        if (result)
                            cameraIntent();

                    } else if (items[item].equals("Choose from Library")) {
                        userChoosenTask = "Choose from Library";
                        if (result)
                            galleryIntent();

                    } else if (items[item].equals("Cancel")) {
                        dialog.dismiss();
                    }
                }
            });
            builder.show();

   private void cameraIntent() {
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(intent, REQUEST_CAMERA);
}


private void galleryIntent() {
    Intent intent = new Intent();
    intent.setType("image/*");
    intent.setAction(Intent.ACTION_GET_CONTENT);//
    startActivityForResult(Intent.createChooser(intent, "Select File"), SELECT_FILE);
}

    @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == Activity.RESULT_OK) {
        if (requestCode == SELECT_FILE)
            onSelectFromGalleryResult(data);
        else if (requestCode == REQUEST_CAMERA)
            onCaptureImageResult(data);
    }

    if (requestCode == PLACE_PICKER_REQUEST && resultCode == Activity.RESULT_OK) {
        hideProgressDialog();
        final Place place = PlacePicker.getPlace(getApplicationContext(), data);
        // final CharSequence name = place.getName();
        final CharSequence address = place.getAddress();
        String attributions = (String) place.getAttributions();
        if (attributions == null) {
            attributions = "";
        }

        editLocation.setText(MessageFormat.format("{0}{1}{2}", String.valueOf(address), getString(R.string.textComma), Html.fromHtml(attributions)));


    }
}

 private void onCaptureImageResult(Intent data) {
    Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    thumbnail.compress(Bitmap.CompressFormat.JPEG, 90, bytes);

    File destination = new File(Environment.getExternalStorageDirectory(),
            System.currentTimeMillis() + ".jpg");

    FileOutputStream fo;
    try {
        destination.createNewFile();
        fo = new FileOutputStream(destination);
        fo.write(bytes.toByteArray());
        fo.close();

    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

    ivImage.setImageBitmap(thumbnail);
}

private void onSelectFromGalleryResult(Intent data) {
    Bitmap bm = null;
    if (data != null) {
        try {
            bm = MediaStore.Images.Media.getBitmap(getApplicationContext().getContentResolver(), data.getData());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    ivImage.setImageBitmap(bm);
}

在 Manifest.xml 文件中设置使用权限

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

尝试这个 

Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Complete action using"), SELECT_IMAGE);

当打开另一个应用程序的意图被触发时，android 将显示可以处理此意图的应用程序。这不是可以从应用程序代码中修复的东西。解决方案是将应用程序设置为该特定操作的默认值。

您的问题的答案是自定义网格视图选择。

我找到了一个很好的示例，它可以让您将画廊中的所有图像显示到您的活动中。这是不同的。因为这不会打开其他应用程序。您可以对此代码进行自定义。

示例名称为AndroidGridViewCompatLib

要实现此代码，您需要在布局文件中编写以下代码。

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <Button
        android:id="@+id/doneButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:enabled="false"
        android:text="Done" />

    <com.rokoder.android.lib.support.v4.widget.GridViewCompat
        android:id="@+id/gridView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_above="@id/doneButton"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:choiceMode="multipleChoice"
        android:columnWidth="120dp"
        android:gravity="center"
        android:horizontalSpacing="10dp"
        android:numColumns="auto_fit"
        android:stretchMode="columnWidth"
        android:verticalSpacing="10dp" >
    </com.rokoder.android.lib.support.v4.widget.GridViewCompat>

</RelativeLayout>

以下代码将在您的活动文件中。

@Override
protected void onCreate(Bundle saveInstance) {
    ...
    ...
    gridView = (GridViewCompat) findViewById(R.id.gridView);
    gridView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
    gridView.setAdapter(imageAdapter);
    ...
    ...
}

这里的例子是CHOICE_MODE_MULTIPLE，你也可以设置它CHOICE_MODE_SINGLE。

    button_pick_image.setOnClickListener(view -> start());

    imagePicker.multi(); // multi mode (default mode)

            .showCamera(true) // show camera or not (true by default)
            .imageDirectory("Camera")   // captured image directory name ("Camera" folder by default)
            .imageFullDirectory(Environment.getExternalStorageDirectory().getPath()) // can be full path
            .start(); // start image picker activity with request code
}
@Override
protected void onActivityResult(int requestCode, final int resultCode, Intent data) {
    if (ImagePicker.shouldHandle(requestCode, resultCode, data)) {
        images = (ArrayList<com.esafirm.imagepicker.model.Image>) ImagePicker.getImages(data);
        printImages(images);
        return;
    }
    super.onActivityResult(requestCode, resultCode, data);
}

private void printImages(List<com.esafirm.imagepicker.model.Image> images) {
    if (images == null) return;

    StringBuilder stringBuffer = new StringBuilder();
    for (int i = 0, l = images.size(); i < l; i++) {
        stringBuffer.append(images.get(i).getPath()).append("\n");
    }
    textView.setText(stringBuffer.toString());
}

}
